All three were rushed to hospital. Two were taken to the trauma centre at Sunnybrook Hospital and the other to Etobicoke General Hospital. Ali was pronounced a short time later.

Police said an autopsy will be done on Tuesday.

On Sunday, police responded to reports of at least five gun shots heard in the area of Dixon Road and Islington Avenue at 11:40 p.m.

Officers arrived to 1 York Road, Kingsview Village Junior School, and found Ali unconscious and suffering from a gunshot wound.

The two other men were located just south of the parking lot, close to Dixon Road and Wincott Drive. Both had gunshot wounds.

Members of the Emergency Task Force and canine squad were called in to secure the neighbourhood and help in the search for perpetrators.

A man was spotted running north on York Road before he or she got into a small, light-coloured vehicle, according to Toronto police homicide Det. Steve Matthews.

The man was described as a five foot seven, in his 20s, with a slim build. He was wearing all black clothing.

Matthews said the school has security cameras and police have obtained footage from the area.

At a news conference early Monday, he appealed for any other witnesses or anyone with potentially valuable video of the attack to contact police.

It's too early to know what the men were doing in the parking lot at that time, Matthews said.

"Hopefully, when we speak to the other victims we can get a better understanding of what happened," he told reporters.

None of the three victims were previously known to police, Matthew added.

This is the second shooting in the Dixon Road and Islington Avenue area in five days. On Thursday, Abdulkadir Bihi, 29, was found in a car near the intersection with serious gunshot wounds. He died in hospital.
